The context is about the time up until now - the very same context that Wenger uses to say, "thanks you've won us things but you're over 30 mow and things have changed". The context is the shambolic recruitment policy sine Dein left.
If a friend lets you down 10 times, it wears you down. Even if for the last 6 months he's been ok once you see the signs of the same thing happending again, it's not like a clean slate - what's gone on before informs what happens now and how you react.
In turn, I think it's misguided to just talk about January. The thing that persistently keeps us in the top four (apart from in most years just having the 3rd biggest wage bill - paupers that we are smashing spurs out of the park

), is the thing that stops us from winning the league and it's painful to watch. If we changed manager, there's of course the chance of a Moyes. But there's also the chance of a Guardiola.
Unfortunately, the club has in hoodwinked our fans to the point that they are so frightened of falling out of the champions league, they are not prepared to risk a manager who might take us further and develop all of the good foundations laid by Wenger but have a different (better) recruitment, tactics and training policy.
I'm a cynical old

but even I let my guard down at times and try to believe that Wenger has changed things. But, deep down I know that he can't win us the league again. Wheeling out the players and other staff to tell us the opposite just make me firmer in my belief.
